System Requirements Document (SRD)

Project Name: prism-app

1. Introduction

The prism-app is a simple, user-friendly todo application designed to streamline task management for users in the US. The app will feature a clean, intuitive interface and will focus on essential functionalities such as authentication, task creation, updating, deletion, and viewing. With a maximum of 2-3 pages, the app aims to deliver a seamless experience for users who want to organize their daily activities efficiently.

2. System Overview

The prism-app will be a lightweight web application accessible via desktop and mobile browsers. It will allow users to create, manage, and track their tasks with minimal effort. The system will include user authentication to ensure data privacy and security. The app will be optimized for performance and usability, adhering to locale-specific defaults such as US time zones and date formats.

3. Functional Requirements

• As a User, I should be able to sign up and log in securely.
• As a User, I should be able to create new tasks with a title and description.
• As a User, I should be able to view all my tasks in a list format.
• As a User, I should be able to edit the details of an existing task.
• As a User, I should be able to delete tasks I no longer need.
• As a User, I should be able to mark tasks as complete or incomplete.

4. User Personas

1. User

• Description: The primary user of the application who will manage their tasks.
• Goals: Organize daily activities, track progress, and maintain productivity.
• Pain Points: Difficulty in managing tasks efficiently without a simple, intuitive tool.

2. Admin (Optional for future scalability)

• Description: A potential role for managing user accounts and monitoring app usage.
• Goals: Ensure smooth operation of the app and address user issues.
• Pain Points: Managing multiple user accounts and ensuring system stability.

5. Visuals Colors and Theme

The prism-app will adopt a modern, minimalistic design with the following color palette:

• Primary Color: Sky Blue (#87CEEB) — for buttons and highlights.
• Secondary Color: White (#FFFFFF) — for backgrounds and text areas.
• Accent Color: Deep Gray (#2F4F4F) — for text and icons.
• Success Color: Green (#32CD32) — for task completion indicators.
• Error Color: Red (#FF4500) — for error messages.

The theme will focus on simplicity and clarity, ensuring users can navigate the app effortlessly.

6. Signature Design Concept

The prism-app will feature a dynamic task dashboard as its signature design concept.

Concept Details:

• Homepage Design:
  The landing page will showcase a live task board with subtle animations. Tasks will appear as interactive cards that users can drag and drop to reorder or categorize.
• Micro-Interactions:
  • Hovering over a task card will reveal quick action buttons (edit, delete, mark complete).
  • Completed tasks will "fade out" with a satisfying checkmark animation.
• Transitions:
  Smooth page transitions with a sliding effect when navigating between the dashboard, task creation, and user settings pages.
• Color Shifts:
  The background will subtly shift between light blue and white gradients, creating a calming effect for users.
• Interactive Features:
  A progress bar at the top of the dashboard will visually represent the percentage of tasks completed.

This design will make the app visually appealing and engaging, ensuring users feel motivated to interact with their tasks.

7. Non-Functional Requirements

• Performance: The app should load within 2 seconds on standard US internet speeds.
• Scalability: The system should support up to 10,000 users without degradation in performance.
• Security: User data must be encrypted both in transit and at rest.
• Accessibility: The app must be WCAG 2.1 compliant to ensure usability for people with disabilities.
• Localization: Default to US time zones and date formats (MM/DD/YYYY).

8. Tech Stack

9. Assumptions and Constraints

Assumptions:

• Users will primarily access the app via desktop and mobile browsers.
• The app will not require advanced features like team collaboration or integrations in its initial version.
• The user base will be limited to the US for the initial launch.

Constraints:

• The app must be limited to 2-3 pages to maintain simplicity.
• Development must adhere to the specified tech stack for compatibility and scalability.
• The app must be lightweight and optimized for performance.
